Replace the lcd display

hi,what about replacing the power supply for the lcd panel.

Sounds like you have power but no backlight. If you use a repair service like Nationwide, it may be cheaper to just get an entire panel. I had the same problem a few months back. Panel fixed it.

Turn VR 911 to desired brightness located under control panel.

teckat there are two VRs located under the control panel,VR1 VR2 respectively...and these VRs are located in pcb FG5-5202..but not the VR 911 as you have mentioned..
